> @sweb what is the status of this PR? Are you blocked? If you just haven't had time or inclination to make changes, that is fine (I totally understand) I just wanted try and clear the PR queue @alamb Sorry for the late response - I did not have enough time to continue with this and did not see your message. However, I am currently blocked on one front: I have created a new kernel function with the following signature: ``` fn regexp_match(array: &Array, pattern: &str) -> Result<ArrayRef> ``` where `ArrayRef` is a `GenericListArray`. This is my attempt to get closer to the Postgres functions. However, I do not seem to understand, how I can define a return type appropriate for `ListArray` for a DataFusion function. To be more specific: When I try to define the return type of `DataType::List` in `functions.rs` I need to create a `Box<Field>` and I am not sure whether it makes sense to create it here - e.g. what should be the name of the field? If you have some pointers for this, I would be very grateful - I was not able to find something similar yet. I have added my current state, which kind of works but I am not too sure that what I am doing there is correct. Again, apologies for the late response. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
